For security reasons, Windows Server 2012 by default has enabled Structured Exception Handling Overwrite Protection (SEHOP) for all applications and services. This can lead to problems when running games and applications. In case you encounter applications crashing with exception code 0xC0000005 (EXCEPTION_ACCESS_VIOLATION), cure use the steps below and the Disable DEP page to disable these security features.

It is better to delete a value rather than setting it as 1.
Because, when it disabled explicitly, it will become disable also in few process of enable implicitly.
(It is similar to the relationship of OptOut, OptIn and AlwaysOff of DEP.)
